Back end printing label generating application for PHP MySql shopping cart

Back end printing mod or application for X-Cart (a php shopping cart running on MySql) for label generation makig USPS (US POstal) zebra terminal labels. ## Deliverables When an order is placed by a customer in our XCart back-end we can select all packages / orders shipping by the United States Postal Service method and generate an .EPL file that contains their shipping labels. In our current system, this .EPL file is then opened using Endicia's Dazzle software where we can see how the labels will look and appear, customize their design, and then print them using our Thermal LP2844 printer without postage costs. The Dazzle software evaluates whether or not the USPS package is Priority Mail, First Class Mail etc. and automatically selects the right label layout for us. After printing the labels, a .XML file containing all the USPS tracking numbers is produced that we then upload to our store for our customers to use. In our new software we need: 1. Ability to download an .EPL file that can be interpreted as label and printed on LP2844 Zebra printer. 2. Ability to process batches of USPS orders - multiple orders at one time 3. Must not require any additional input to produce and print labels 4. Must receive and produce a .XML file containing all USPS tracking numbers so they may be uploaded to the store 5. Be fully compatible within X-Cart eCommerce stores version 4.1.19 - 4.4.44 if possible 6. Be compatible with Google Chrome, Mozilla Firefox browsers (current and future versions) 7. Automatically update any API changes from the United States Post Office 8. Be compatible with Windows XP and Windows 7 operating environments
